Oncor's residential delivery charge rises to 6.8673¢ per kWh from October 4, 2026

Oncor, the utility that owns the poles and wires across much of North and Central Texas, raised its residential per-kWh delivery charge on October 4, 2026. According to Oncor's Tariff for Retail Delivery Service (checked October 9, 2026), the charge went from 6.0295¢ to 6.8673¢ per kWh, an increase of 0.8378¢ per kWh, or about 13.9%. The monthly charge of $4.06 ($1.48 customer charge plus $2.58 metering charge, effective June 1, 2026) did not change.

Oncor's delivery charges are the same whichever retail provider you choose in its area. If you are not sure who does what, see our guide to your utility vs your retail provider.

What changed

Oncor's residential per-kWh delivery charge is the sum of a base charge and several riders, each on its own tariff sheet. Two of them changed on October 4, 2026: the Transmission Cost Recovery Factor (TCRF) and the Distribution Cost Recovery Factor (DCRF).

The tariff lists each component separately; the totals are our sum. The earlier total, 6.0295¢, is the residential volumetric charge in the PUCT's monthly report for Oncor "as of October 1, 2026", a date before the October 4 change.

According to the tariff, the TCRF adjusts for changes in wholesale transmission costs since Oncor's last rate case, and the DCRF recovers distribution costs not included in Oncor's last general rate case. The tariff sheets do not name the proceeding that set the October 4 values, so we do not attribute the change to a specific case here.

What it adds to a bill

These are our estimates of the delivery part of a monthly bill only: $4.06 plus usage times the per-kWh charge. They leave out taxes, other fees and your provider's own energy and base charges.

The change column is calculated before rounding (0.8378¢ times usage), so it can differ by a cent from the difference of the rounded totals. The "through Oct 3" amounts match the PUCT report's average residential bills for Oncor.

As an illustration, if the 0.8378¢ difference applied to 12,000 kWh over a year, it would add about $100.54. Delivery charges change during the year (see below), so this is not a forecast. We have not checked how a billing cycle that includes October 4 is split between the two rates; your provider can tell you.

Can a fixed-rate plan pass it on?

Generally, yes. The PUCT's rule 16 TAC §25.475(b)(5) defines a fixed rate product as one whose price is the same throughout the contract term, "except that the price may vary from the disclosed amount solely to reflect actual changes in TDU charges", changes to ERCOT or Texas Regional Entity administrative fees, or changes from new laws. Under §25.475(d)(2)(B), each bill for a fixed rate product must either show such price changes on separate line items or include a conspicuous notice that the amount billed may include price changes allowed by law or regulatory actions.

Plans handle this differently. Many Electricity Facts Labels (EFLs) we read say delivery charges are passed through, while at least one Oncor-area plan in our data bundles delivery charges into a single price. Check your EFL and terms of service to see what yours says.

What our data shows

As of October 9, 2026, there were 203 active Oncor-area plans in the Power to Choose export we import. Reading each plan's EFL:

• 143 show the new charge: 140 print 6.8673¢ per kWh and 3 print it rounded to 6.867¢.
• 11 still print 6.0295¢, the charge in effect before October 4. They come from three providers: Good Charlie & Co (6), Champion Energy Services (3) and Heritage Power (2).
• 49 have no separate per-kWh delivery charge that our EFL reader found; one of these says delivery charges are bundled into its price.

Plan prices on Power to Choose and on EFLs include delivery charges. On a label that still uses 6.0295¢, the average prices were calculated with the old delivery charge. If you are looking at one of those plans, ask the provider which delivery charge it will bill.

What comes next

• Rider IS ends after December 2026. The tariff says this interim surcharge (0.3633¢ per kWh for residential customers) "shall remain in effect through December 2026", and that any over- or under-recovery will be reconciled in a future proceeding. The tariff does not say what the residential total will be from January 2027; other components can change too.
• Rider MG applies only in December. The tariff's Mobile Generation rider is charged each December; its latest residential value in the tariff is 0.1027¢ per kWh, effective December 1, 2025.
• Rider RCE remains until $8,291,399 in approved rate case expenses has been billed, which the tariff estimates at about one year from June 1, 2026.

We track Oncor's delivery charges in our data and will update this article when the tariff changes.

How to check and compare

• On your bill: look for the delivery or TDU line, which may be labeled "TDU delivery charges" or name Oncor. For usage after October 4, the per-kWh part should reflect 6.8673¢. Bill formats differ by provider.
• When comparing plans: the delivery charge is the same for every provider in Oncor's area, so the differences between plans come from each provider's energy charge, base charge and any bill credits. Compare Oncor-area plans by estimated annual cost on your own usage.
• For the data: see our rate index, or the delivery-charges dataset in our market data API, which lists the PUCT and EFL figures with their sources and dates.
